blueroomelectronics Posted May 2, 2007 Report Share Posted May 2, 2007 It's not a working design. try switching something not lethal first. The gate has no point of reference.Also RS is not a great source of HV electronics.Is the 500V AC or DC?You need isolation between your 10V and the 500V like an optoisolator.500V can mess up your day, life etc...
